• How to match a variable list of items separated by commas

  - by user261915

  I want to turn something like this CS 240, CS 246, ECE 222, ... (more or less); Software Engineering students only into ('CS 240', 'CS 246', 'ECE 222', 'ECE 220') in Python, code that matches a single course looks like >>> re.search('([A-Z]{2,5} \d{3})', 'SE 112').groups() ('SE 112',) I prefer a regular expression only method because I have a bunch of other alternate reg exps using '|' to combine them. However, a method with split is acceptable.

• Adding Related Entities without using navigation properties

  - by Barisa Puter

  I have the following classes, set for testing: public class Company { [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int Id { get; set; } public string Name { get; set; } } public class Employee { [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int Id { get; set; } public string Name { get; set; } public int CompanyId { get; set; } public virtual Company Company { get; set; } } public class EFTestDbContext : DbContext { public DbSet<Employee> Employees { get; set; } public DbSet<Company> Companies { get; set; } } For the sake of testing, I wanted to insert one company and one employee for that company with single SaveChanges call, like this: Company company = new Company { Name = "Sample company" }; context.Companies.Add(company); // ** UNCOMMENTED FOR TEST 2 //Company company2 = new Company //{ // Name = "Some other company" //}; //context.Companies.Add(company2); Employee employee = new Employee { Name = "Hans", CompanyId = company.Id }; context.Employees.Add(employee); context.SaveChanges(); Even though I am not using navigational properties, but instead I've made relation over Id, this somehow mysteriously worked - employee was saved with proper foreign key to company which got updated from 0 to real value, which made me go ?!?! Some hidden C# feature? Then I've decided to add more code, which is commented in the snippet above, making it to be inserting of 2 x Company entity and 1 x Employee entity, and then I got exception: Unable to determine the principal end of the 'CodeLab.EFTest.Employee_Company' relationship. Multiple added entities may have the same primary key. Does this mean that in cases where foreign key is 0, and there is a single matching entity being inserted in same SaveChanges transaction, Entity Framework will assume that foreign key should be for that matching entity? In second test, when there are two entities matching the relation type, Entity Framework throws an exception as it is not able to figure out to which of the Companies Employee should be related to.

• Internal classes with ADO.NET Entity Framework

  - by Regent

  I'm using Entity Framework for creation of my Data Access Layer and I want for all of my classes to be internal. I know it is possible to manually assign it manually in the designer for each class. But looks like it also requires to set internal modifier for each single property in every class! I have about 30+ entities and it will be a huge work to do. Do you know any ideas how to set a 'default access' for the entire model?

• Is there a simple way to determine type size in C#?

  - by archimedes

  Is there a way to say something like: sizeof(type)? Or type.Size? Right now I am looking at using code like: if (type.Equals(typeof(int))) return sizeof(int); else if (type.Equals(typeof(long))) return sizeof(long); etc, etc, for every single data type. There must be an cleaner solution, no?

• How many keys are too many in memcached?

  - by jack

  I currently have about 650,000 items in memcached (430MB memory used) and the number is still increasing. It's expected to exceed 1,000,000 items before going flat. Current hit/miss ratio is 25:1 so the efficiency is pretty good. I just wanted to ask is one million items in memcached on single server too many? If no, how many is too many?

• Concurrent processes do not utilize all available CPU

  - by metdos

  I run some processes on an EC2 cc2.8xlarge instance which has 32 virtual processors. For some type of processes, when I run 16 processes on parallel, all of them use 100% of CPU cycles. But for other type of processes, they are not using 100% CPU and they finish considerably slower than a single thread. There is no time spend on IO and all data is served from memory. Do you have any idea about the reason of this problem?

• xdebug profiler output strange results

  - by nic28

  I'm using xdebug to profile some PHP code on Windows and using WinCacheGrind/Webgrind to analyse the output, but I'm getting some strange results. Specifically, the total cumulative time for a single method is greater than 100%! How is it possible that more time is spent executing this function's code and all the functions that it calls than the total time it took to execute the whole script? What am I missing here?

• Making many network shares appear as one

  - by jimbojw

  Givens: disk is cheap, and there's plenty lying around on various computers around the corporate intranet redundant contiguous large storage volumes are expensive Problem: It would be fantastic to have a single entry point (drive letter, network path) that presents all this space as one contiguous filesystem, effectively abstracting the disk and network architecture from the paths presented to users. Does anyone know how to implement such a solution? I'm open to Windows and non-windows solutions, free and proprietary.

• How to add a button on outlook toolbar to a custom form?

  - by eqbridges

  Hi I have an Outlook form that I'd like to provide ready access to by adding a button or link to it on the outlook toolbar. How can I customize the toolbar to do this? Essentially, a single click of the button on the toolbar should bring up the custom form. This should work in Outlook 2003 and 2007 (preferably). If it only works in 2007 that would be acceptable. Thanks!
